Abstract

ABSTRAK : Penyu laut merupakan hewan yang menghabiskan hampir seluruh hidupnya di bawah permukaan laut. Penyu laut dikategorikan hewan yang terancam punah. Jenis Penyu Lekang (Lepidochelys olivacea) adalah organisme laut yang tergolong dalam kategori terancam punah. Salah satu upaya untuk melestarikan populasi penyu adalah dengan melakukan pelepasan tukik. Namun keberhasilan setelah pelepasan tukik pada umumnya tidak pernah diketahui. Oleh karena itu, perlu adanya usaha untuk mempersiapkan tukik sebelum dilepas ke laut, sehingga membantu tingkat kelangsungan hidup tinggi. Aspek yang sampai saat ini belum diketahui adalah kebutuhan nutrisi yang tepat untuk menunjang pertumbuhan tukik. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pakan buatan yang berbeda terhadap laju pertumbuhan panjang karapas, lebar karapas, dan bobot pada tukik Penyu Lekang. Penelitian ini dilakukan pada bulan Januari 2016 di Turtle Conservation and Education Center, Bali. Metode penelitian yang digunakan adalah metode eksperimental dengan menggunakan rancangan acak lengkap (RAL) 3 perlakuan dan 3 kali ulangan. Perlakuan yang diberikan berupa perbedaan sumber bahan baku pakan yang berbeda pada tukik adalah A=tepung ikan 40%, B=tepung ikan 35%, dan C=tepung ikan 30%. Jumlah pakan yang diberikan sebesar 5% dari bobot tukik per hari. Pemberian pakan dilakukan 2 kali sehari pada waktu pagi jam 09.00 WITA dan sore hari jam 16.00 WITA. Pergantian air dilakukan setiap hari pada pagi hari jam 07.00 WITA. Hasil pemberian pakan buatan dengan jumlah tepung ikan yang berbeda memberikan pengaruh sangat nyata (p<0,01) terhadap laju pertumbuhan spesifik panjang karapas, lebar karapas, dan bobot tukik Penyu Lekang. Pakan buatan yang paling baik di antara perlakuan yang diterapkan dicapai oleh pakan buatan dengan kandungan tepung ikan 40%. Pakan buatan dengan kandungan tepung ikan 40% menghasilkan tingkat laju pertumbuhan spesifik panjang karapas 0,48%/hari, lebar karapas 0,56 %/hari, dan berat tukik 1,13 %/hari. ABSTRACT : A sea turtle is an animal that spends most of its life under the sea. Sea turtles also belongs to the category of extinct animals. Olive ridley sea turtle (Lepidochelys olivacea) is a marine organism belonging to the endangered category. One of the efforts to conserve the turtle population is to release the hatchlings. But the succeed after releasing the hatchlings is generally not recognized. Therefore, there is a need to prepare for the hatchlings before being released into the sea to help the survival rate improved. An aspect which is still unrecognized is the need to support proper nutrient for the hatchlings growth. This study aimed to determine different concentrations in artificial feed to the growth rate of hatchling turtles carapace length, carapace width, and weight. This study was conducted in January 2016 in Turtle Conservation and Education Center, Bali. The method used was an experimental method with completely randomized design three treatments and three replications. The treatment given in the form of different sources of raw materials of different feed to hatchlings is A = the flour fish 40%, B = the flour fish 35%, and C =the flour fish 30%. The weight of the feed given was 5% of the hatchlings weight. The feeding was done twice a day, at 09.00 a.m. and at 04.00 pm. The substitution of water was done every day at 07.00 pm.

Abstract

Caulerpa racemosa is a type of seaweed that has potentially to be cultivated because very popular and liked by most peoples. Japan and Philipines made the C. racemosa as one of the aquaculture commodities. C. racemosa culturing has not been done in Indonesia. Usually people just take directly from nature thus diminishing its presence in nature. Seaweed farming important to be done to inhance the production of seaweed. This study was conducted in May - July 2011 in a wet lab, University of Diponegoro Marine Station Teluk Awur, Jepara. The research method used an experimental method with a completely randomized design. This study used four treatments and one control, each of which was repeated three times. Rearing media using sea water plus nitrogen with different concentrations, namely: A (0 μM), B (50 μM), C (100 μM), D (150 μM) and E (200 μM). The results showed that the addition of urea nitrogen was significant difference on the growth of C. racemosa var. uvifera (p <0.01). The average of weight gain of C. racemosa var. uvifera for 42 days, as follows: A = 3.38 ± 0.089 g, B = 3.46 ± 0.14 g; C = 3.59 ± 0.18 g; D = 3.44 ± 0.11 g and E = 3.42 ± 0.10 g. Specific growth rate of C. racemosa var. uvifera generated during the study, namely: A 0.60 ± 0.015 % per day; B of 0.94 ± 0.012% per day; C of 1.36 ± 0.024% per day; D of 0.84 ± 0.026% per day and E of 0.75 ± 0.028% per day.

Abstract

ABSTRAK: Rajungan (P. pelagicus, Linnaeus, 1758) adalah salah satu hasil perikanan utama di Betahwalang, Demak. Penangkapan rajungan diduga dilakukan secara intensif oleh nelayan di Des Betahwalang, maka diperlukan langkah pengelolaan yang tepat untuk menjaga kelestarian dan konservasi rajungan. Informasi aspek morfometri rajungan bias digunakan sebagai salah satu acuan dalam pengelolaan rajungan berkelanjutan. Tujuan penelitian adalah untuk mengkaji tingkat kematangan gonad dan morfometri rajungan yang dilaksanakan pada bulan Juli – September 2019 di Desa Betahwalang, Demak. Penelitian menggunakan metode survey dengan analisis yang bersifat deskriptif yang dilakukan secara “time-series”. Pengamatan sampel rajungan sebesar 10% dari hasil tangkapan yang didaratkan oleh setiap nelayan di pengepul rajungan. Total rajungan yang diamati 5.480 ekor terdiri dari betina 2.960 ekor dan jantan 2.388 ekor. Hasil penelitian menunjukkan pertumbuhan rajungan jantan bersifat allometrik positif, sedangkan rajungan betina cenderung bersifat allometrik negatif dengan seks rasio relatif seimbang. Rajungan betina diduga mengalami pertama kali matang gonad pada selang kelas lebar karapas 70 – 79 mm. Sampel pengamatan fekunditas dan kematangan telur pada 126 ekor rajungan betina bertelur. Kematangan telur dilihat dari pigmen warnanya secara berurutan mulai pigmen warna kuning, orange, coklat dan hitam, serta berdasarkan ukuran diameter telur. Fekunditas telur memiliki korelasi yang sangat kuat terhadap lebar karapas yang berarti semakin besar ukuran rajungan, maka jumlah telur semakin banyak. Selama penelitian masih ditemukan rajungan “undersize” sebesar 18% (981 ekor) dan rajungan betina bertelur sebesar 24% (716 ekor), yang berarti nelayan di Desa Betahwalang belum menerapkan kriteria dan ukuran layak tangkap sesuai dengan peraturan yang berlaku.ABSTRACT: Blue swimming crab (P. pelagicus, Linnaeus, 1758) is one of main fisheries products in Betahwalang, Demak. High-intensity levels of catching the blue swimmer crab by fisherman may need sustainable management to protect and conserve the population. The purpose of this study was to determine about gonad maturity level and morphometrical aspect of blue swimming crab started from July – September 2019. There’s a descriptive survey method used in this study with time-series observations. The sample size is about 10% of the total number landed crab from each fisherman. The total sample are 5.348 that consist of 2.960 female crabs and 2.388 male crabs. The results showed the male crabs has a positive allometric on growth parameters, but the females have an allometric positive and negative growth parameters, and balanced sex-ratio. Female crabs may reach the first matured gonad level between 70 – 79 mm of carapace width. Fecundity and egg’s maturity observation used 126 berried female crabs. The egg’s maturity based on the pigment color started from yellow, became orange, brown and black also by egg diameter increase. The analysis showed that female crab fecundity has a strong correlation to the increase of carapace width, which means carapace width increase followed by egg’s amount increasing. During the study, it was found about 18% (981 crabs) the undersize crabs (<100 mm) and 24% (716 crabs) the berried female crabs, which means the Betahwalang fisherman hasn’t applied the rule yet.
